I don't fully understand your data layout, but this example should help you do what you want:

% Create some example data
dateList = {'2001-01-01','2001-02-01','2001-03-01','2001-04-01','2001-05-01','2001-06-01','2001-07-01','2001-08-01','2001-09-01','2001-10-01','2001-11-01','2001-12-01'}';
% Create matrix with numeric year,month,day, etc
dateVector = datevec(dateList);
% Isolate the month  
monthVector = dateVector(:,2);
% Find the months from May through Oct
indexToMayThruOct = ismember(monthVector,[5:10]);
% Purge those data from the original list  
dateList(indexToMayThruOct) = [];

@devendra, is your data really 4-dimensional, or is it actually 2-dimensional with 4 columns?

What is the variable type that stores your data? Is it a cell array?

Maybe this is closer to what you need. You need to try to understand the answer, not just apply it blindly.

Also, it would be useful for you to post a small example of your data.

% Create matrix with numeric year,month,day, etc
dateVector = datevec(prec(:,3));
% Isolate the month  
monthVector = dateVector(:,2);
% Find the months from May through Oct
indexToMayThruOct = ismember(monthVector,[5:10]);
% Purge those data from the original list  
prec(:,indexToMayThruOct) = [];
